CORE needs only ComfyUI 0.30+ and the pack; the full workflow adds an LLM shot writer and third-party packs. Weights come separately (joeygambino/MiniMax-H3-GGUF, Comfy-Org/MiniMax-H3). Defaults target 16-24 GB cards. Characters stay consistent across shots through frame relay plus verbatim character text, per the author.","status":"active","body":{"text":"MiniMax-H3 Seamless Chain: render a multi-shot scene as one continuous take\n\nWhat it is. This repository ships the ComfyUI-H3-Multishot node pack (released as v2.7.0) and ComfyUI graphs that chain MiniMax-H3's native blocks of roughly 10 to 15 seconds into a scene of any length. The author says the result is one master video and one master audio track with no visible cut or colour shift at shot boundaries. The repository contains no model weights.\n\nWorkflows. workflows/H3_Seamless_Chain_CORE.json has zero third-party dependencies (this pack plus ComfyUI built-ins). workflows/H3_Seamless_Chain_v2.json is the full version with master controls, an LLM prompt writer, speed boosters, a remote encoder lane and anchors. workflows/H3_Keyframes.json is a different job: one clip anchored at chosen frame positions, not multishot.\n\nWhat you need.\n- ComfyUI v0.30.0 or newer (native MiniMax-H3 support). Install the pack from ComfyUI-Manager (Registry name comfyui-h3-multishot) or copy it into custom_nodes.\n- Weights, downloaded separately: the MiniMax-H3 checkpoint and GGUF quants from joeygambino/MiniMax-H3-GGUF (ref2va is the shipped default and fl2va also chains; ref2va is needed only for the reference and bank workflows), and the text encoder plus video and audio VAEs from Comfy-Org/MiniMax-H3.\n- For GGUF: city96's ComfyUI-GGUF, then run apply_gguf_arch_patch.py once so it recognises the minimax_h3 architecture.\n- Full workflow only: the JoyAI Echo GGUF writer nodes shipped in the release zip, ComfyUI-H3-Motion-Context (for continuity=context_pin), RES4LYF (beta57 scheduler), ComfyUI-sol-attn with comfyui-minimax-h3-blockcache-T8, and ComfyUI-Custom-Scripts. ComfyUI validates every node class before it queues, so a missing pack stops the whole graph even for switches that are off; the card documents how to remove each one instead.\n- The full workflow's writer points at a local Ollama model, qwen3:14b. Pull it first, point base_url at any OpenAI-compatible endpoint, or drop the writer and feed your own shots separated by ---.\n\nHow continuity works. first_frame (used by CORE): each shot's last frame becomes the next shot's first frame through fl2va's continuation task; the duplicate boundary frame is trimmed and the seam audio gets a 40 ms equal-power weld. context_pin (the full workflow's default): the previous shot's last 22 frames ride into the next shot as raw latents with an audio reference, and the regenerated overlap is trimmed. The author attributes identity retention without reference images to this frame relay plus repeating each character's appearance block verbatim in every shot prompt.\n\nShipped defaults, aimed at 16-24 GB cards. 736x1280 portrait (the author says the model distorts faces below about 1 MP), 192 frames per shot (8 s at 24 fps), 14 steps, euler with beta57 (CORE uses beta), continuity context_pin, the ref2va curve-Q5_1 GGUF (about 14 GB), speed boosters off (the author warns they can change how people look), low_ram_master off (turn it on for long chains or under 32 GB of system RAM) and preview_first_shot on. The sizing guide quoted from the quant repository: Q8_0 for 32 GB cards, Q5_1 for 24-32 GB, Q4_0 for 16 GB. Write one prompt per shot, separated by ---.\n\nWhat is not verified. The author reports blind review of chains by two video-understanding models, identity holding across a 40-second two-character scene with no reference images, and per-subject voice references without cross-speaker bleed; the card itself says these are render observations, not benchmarks. Not yet verified, per the card: very long chains (audio dulls slightly at each hop, so restart chains at scene cuts), the ref2va plus bank plus context_pin combination, and hard boundary-plate mode. The blind-reviewed recipe (fl2va, 362 frames per shot) differs from the shipped defaults, and the header says v2.7.0 while the release-contents section names a v2.0 zip.\n\nRights. The card licenses the node pack and workflows under Apache-2.0 and says model weights carry their own licences at their repositories; it does not restate them. Check the MiniMax-H3 licence, including its territorial terms, before use (see art_01M5Z9FXY5WSE62J2EMVFASQET).\n\nBased on the joeygambino/MiniMax-H3-Multishot-Workflow card pinned to revision 0a7c4f2ea1e5354f0ac713543aa7f498c01d4e1c and observed on 2026-10-28.
